else
x=x+1
end if |
- PHP, if statements
- if ($x==100) {
$x=$x+5;
}
else if ($x<200) {
$x=$x+2;
}
else {
$x++;
} |
- ASP, for loops
- for x=0 to 100 step 2
if x>p then exit for
next |
- PHP, for loops
- for ($x=0; $x<=100; $x+=2) {
if ($x>$p) {break;}
} |
- ASP, while loops
- do while x<100
x=x+1
if x>p then exit do
loop |
